Description

Non Film Forming Deep Penetrating Nano Surface Protectant DK 900™

DK 900 is a dual component, water reducible, multifunctional, concrete protectant that repels oil, salt, de-icing agents, and water. With its roots in Urethane and Acrylic nanotechnology, DK 900 is designed to be minimal/non-film forming on concrete and natural stone surfaces. Nanotechnology allows for deep penetration into porous substrates DK 900 is excellent as a maintenance guard on existing slabs. DK 900 is suitable for numerous interior or exterior surfaces including but not limited to
polished concrete, broom finish concrete, stained concrete, decorative concrete, exposed concrete, honed and polished travertine, white Carrera marble, natural stone, pavers, synthetic stone, unglazed tile, and brick. It excels in performance on vertical and horizontal surfaces.

Examples of the vertical surface include but are not limited to Precast walls, block walls, decorative concrete walls, and paver retaining walls. Suitability tests are recommended for each substrate to help determine coverage rates. Can be applied to fresh concrete as soon as 14 days, 24-48 hours for thin overlayment’s.

How to Apply SureCrete DK 900 Nano Protectant (POLISHED SURFACES)

Surface Preparation:Clean: The surface must be free of dust, dirt, oil, grease, paints, glues, film-forming sealers, curing agents, efflorescence, chemical contaminants, rust, algae, mildew and other foreign matter that may serve as a bond breaker or prevent proper adhesion or penetration.Patching: Joints sealants, caulking, and non-cement-based patching materials will not accept DK 900. Ensure joints, caulking and patching have been done prior to application to avoid surface preparation in these areas after application. Cement based repair work should be accomplished 24 hours prior to application

Mixing SureCrete’s DK 900 Nano Concrete Protector:

1. Organize the mixing station that neither has to relocate, nor block the progress of an application.2. The product will become unstable after opening, open only when ready to use.3. Pour contents of part B into part A’s 1 gallon (3.7 liters) can.4. Mechanically mix complete kit both parts A and B for 3 minutes at slow to medium speed with a jiffy style mixer.5. Add mixed components into a 3-gallon bucket.6. Add water to the 3-gallon mark approximately 1 ½ “(3.8 cm) from overflow).7. Mechanically mix for 3 minutes at slow to medium speed with a jiffy style mixer.

Applying the First Coat:
1. Pour catalyzed, water reduced product into pump-up sprayer equipped with a cone tip.
2. Spray light mist of product on the intended substrate. The surface should be SSD at 100% coverage avoiding puddles.
3. Using a microfiber applicator, evenly spread product and eliminate any puddling.
4. Allow 1-3 minutes for product to penetrate the substrate.
5. Burnish floor using either a high or low-speed rotational floor machine equipped with 800 – 3000 grit Hurricane Pad. May be used in conjunction with heat reflectors.

Applying the Second Coat
1. Porous areas, areas of heavy traffic, or high levels contamination and staining will require a second application.
2. After 2 hours after the first coat, a second coat may be applied.
3. Second coat applies as described above for first coat.

How to Apply SureCrete DK 900 Nano Protectant (NON POLISHED SURFACES)

Surface Preparation:Clean: The surface must be free of dust, dirt, oil, grease, paints, glues, curing agents, efflorescence, chemical contaminants, algae, mildew and other foreign matter that may serve as a bond breaker or prevent proper adhesion.

Mild degreasers, such as SCR used in conjunction with pressure washing at a minimum of 3500 psi can be used in areas containing heavy grease deposits. Surface areas that are not contaminated can be prepared using
a 4000-psi pressure washer. Use of Dawn dish soap is also an acceptable degreaser for environmentally sensitive areas.

To remove coatings, paint, sealers, glue from concrete, etc. best results are achieved through diamond grinding or shot blasting.

Cured: Any concrete must be sufficiently cured to have complete hydration, approximately 14 days depending on temperatures & humidity. Cement based overlays and restoration products such as Broom Finish
and Couture Concrete Products, typically cure sufficiently within 1-2 days.

Mixing SureCrete’s DK 900 Nano Concrete Protector:

Planning1. Provide for ventilation. Select appropriate PPE. Refer to SDS.2. Mask/shield surrounding areas not intended for coating.Mixing and Handling1. Organize the mixing station that neither has to relocate, nor block the progress of an application.2. The product will become unstable after opening, open only when ready to use.3. Pour contents of part B into short filled Part “A”.4. Mechanically mix complete kit both parts A and B for 3 minutes at slow to medium speed with a jiffy style mixer.5. Catalyzed concentrate = .6 (2.25 liters).6. Pour catalyzed mixture into a 3-gallon bucket.7. Add water to the 3-gallon mark on the catalyzed pail.8. Mechanically mix for 3 minutes at slow to medium speed with a jiffy style mixer, avoiding air entrainment.

Applying the First coat of DK 900 Nano Protectant:

First Coat1. Pour catalyzed, water reduced product into pump-up sprayer equipped with a cone tip.2. Spray light mist of product on the intended substrate. The surface should be SSD at 100% coverage avoiding puddles.3. Allow to soak in, using a lint-free roller, back roll puddles, drips or runs.4. When applying to vertical surfaces begin application from the bottom up to avoid staining form un-noticed drips or runs.

Second Coat1. Porous areas, areas of heavy traffic, or high levels contamination
and staining will require a second application.2. After 2 hours after the first coat, a second coat may be applied.3. Second coat applies in the same manner as described above for first coat.
